Amorphous Alloy Transformer

General

 

An amorphous metal transformer (AMT) is a type of energy efficient transformer found on electric grids. The magnetic core of this transformer is made with a ferromagnetic amorphous metal. The typical material (Metglas) is an alloy of iron with boron, silicon, and phosphorus in the form of thin (e.g. 25 µm) foils. These materials have high magnetic susceptibility, very low co ercivity and high electrical resistance. The high resistance and thin foils lead to low losses by eddy currents when subjected to alternating magnetic fields. On the downside amorphous alloys have a lower saturation induction and often a higher magnetostriction compared to conventional crystalline iron-silicon electrical steel .  An amorphous metal transformer (AMT) is a type of energy efficient transformer found on electric grids.

The main application of FARADY AMTs are the grid distribution transformers rated at about 50-2500 kVA. These transformers typically run 24 hours a day and at a low load factor (average load

divided by nominal load). The no load loss of these transforms makes up a significant part of the loss of the whole distribution net. Amorphous iron is also used in specialized electric motors that

operate at high frequencies of perhaps 350 Hz or more.
